After releasing a stellar debut in 2002 and a slightly lesser follow-up in 2004, Interpol seemed to misplace their focus on 2007’s muddled Our Love to Admire. They’ve reversed that downward slide at last with their fourth album, Interpol. The riffs here are grander, the rhythms more limber, and the melodies more memorably moody than they’ve been in years. Lapsed fans may be surprised to find themselves reminded of why they loved this band in the first place. B+
